openssl -- denial of service

Mitre reports:

OpenSSL through 1.0.2h incorrectly uses pointer arithmetic
for heap-buffer boundary checks, which might allow remote attackers to
cause a denial of service (integer overflow and application crash) or
possibly have unspecified other impact by leveraging unexpected malloc
behavior, related to s3_srvr.c, ssl_sess.c, and t1_lib.c.
